Which EcoBoost did you drive, the 2.7L or 3.5L?
Here's a rear wheel dyno chart from SCT for a bone-stock 5.3L L83 GM engine on 87 octane:
Rear wheel dyno chart from SCT for a bone-stock 3.5L EcoBoost on 87 octane:
Gear ratio plays a *significant* factor - if you're used to 4.10s or even 3.73s with the 5.3L then 3.31s with the 3.5L are gonna feel comparatively anemic - but the powerplants themselves don't really compare.
I test drove a 2019 F150 with 3.5L EB, 10-speed automatic and 3.55s and the butt dyno DEFINITELY felt a difference to my 2017 Silverado...due in no small part I'm sure to GM's gawd-awful torque management tuning.
